# OpenAPI Specification

> Import MIDAS as GPT Actions or generate SDKs

## OpenAPI 3.0

MIDAS provides a full OpenAPI 3.0 specification that can be used to:

* **Import as GPT Actions** — Give ChatGPT direct access to MIDAS financial tools
* **Generate typed SDKs** — Auto-generate client libraries in any language
* **Import into Postman** — Test all endpoints interactively
* **Build custom integrations** — Use with any tool that supports OpenAPI

## GPT Actions setup

1. In ChatGPT, go to **My GPTs → Create a GPT → Configure → Actions**
2. Click **Import from URL** or paste the spec
3. Set the authentication to **API Key** with header `Authorization: Bearer`
4. Your GPT can now make payments, send messages, and negotiate

## SDK generation

Use [OpenAPI Generator](https://openapi-generator.tech/) to create client libraries:

```bash theme={null}
npx openapi-generator-cli generate \
  -i openapi.json \
  -g python \
  -o ./midas-sdk-python
```

Supported languages: Python, TypeScript, Go, Rust, Java, Ruby, and 40+ more.
